thermal: Introduce Qualcomm Thermal Mitigation Device support
The Thermal Mitigation Device (TMD) Service is a QMI service that runs
on remote subsystems (the modem and DSPs) on Qualcomm SoCs.
It exposes various mitigations including passive thermal controls and
rail voltage restrictions.
This series introduces support for exposing TMDs as cooling devices
in the kernel through the thermal framework, using the QMI interface.
Each TMD client is described as a child of the remoteproc node in
devicetree. With subnodes for each control.
This series is based on previous work by Bhupesh Sharma which can be
found at [1]. I'm sending this as a fresh series as it has been a
year since the original version and I have rewritten most of the driver.
